OEM Carrier Defrost Control Board HK32EA007 for Model PH13NB04900GAAAA

This is the genuine OEM Carrier defrost control board (part number HK32EA007), the factory-specified replacement for the Carrier PH13NB04900GAAAA heat pump. The defrost control board manages the automatic defrost cycle — monitoring outdoor coil temperature and initiating timed defrost sequences to melt frost and ice accumulation on the evaporator coil. When this board fails, you'll typically see continuous frost or ice buildup on the outdoor unit, the system stuck in defrost mode, or a complete loss of heating capacity as the coil becomes fully blocked. In cold climates, a failed defrost board can render a heat pump entirely inoperative within hours.

  • Part Number: HK32EA007 | Also cross-references: 1177927, 1173636 | Factory-matched OEM specification for Carrier heat pump systems
  • OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards use factory-calibrated defrost timing and temperature thresholds. Aftermarket boards frequently miscalibrate defrost intervals, causing premature compressor wear or chronic icing.
  • Install Difficulty: 3/5 — Requires disconnecting low-voltage control wiring harness and mounting screws inside the outdoor unit control panel. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter (for verification), camera or phone to photograph wiring before disconnecting. Turn off power at the disconnect and breaker before beginning. Recommend verifying board operation with a full defrost cycle test after installation.
  • Warranty: 1-year OEM manufacturer warranty. In-stock unit ships same business day from our warehouse — get your heat pump back online fast.

Compatibility: Designed for the Carrier PH13NB04900GAAAA heat pump. Also compatible with select Bryant and Payne heat pump models that share the HK32EA007 specification — verify your model's data plate and wiring diagram before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier PH13NB04900GAAAA?
Yes. This is the factory-specified OEM control board for the Carrier PH13NB04900GAAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PH13NB04900GAAAA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
